Answer:

Step-by-step explanation:

yz+4z=z-y²

yz+4z-z=-y²

yz+3z=-y²

z(y+3)=-y²

z=-\frac{y^2}{y+3 }

5x-2y=-6 3x-4y = -26​
snow_tiger [21]

For this case we must solve the following system of equations:

5x-2y = -6\\3x-4y = -26

We multiply the first equation by -2:

-10x + 4y = 12

We add the new equation with the second one:

-10x + 3x + 4y-4y = 12-26

We have different signs subtracted and the sign of the major is placed:

-7x = -14\\x = \frac {-14} {- 7}\\x = 2

Now we find the value of the variable "y":

3x-4y = -26\\3 (2) -4y = -26\\6-4y = -26\\-4y = -26-6\\-4y = -32\\y = \frac {-32} {- 4}\\y = 8

Thus, the solution of the system is given by:

(x, y) :( 2,8)

Answer:

(x, y) :( 2,8)

-8
Step 1) Subtract 3 from both sides of the equation
Step 2) Add 4W to both sides of the equation
Step 3) Divide both sides of the equation by the same factor

Help me on number problem 4 please
kakasveta [241]

Answer:

y = -1/4x + 3

Step-by-step explanation:

Because you are finding the perpendicular slope, you need to find the negative reciprocal of the original line, which would be -1/4. You then use point slope form to find the y-intercept with the slope and given point:

y - 5 = -1/4(x + 8). That equals to y = -1/4x + 3.

So the equation of this line is y = -1/4x + 3.
